Chapter 3. Physical specifications PC 300PL - tower Dimensions Height: 492 mm (19.4 in.) Width: 200 mm (7.9 in.) Depth: 445 mm (17.5 in.) Weight Minimum configuration as shipped: 15 kg (33 lb) Maximum configuration: 17.3 kg (38 lb) Environment Air temperature: - System on: 10° to 35°C (50° to 95°F) - System off: 10° to 43°C (50° to 110°F) - Maximum altitude: 2134 m (7000 ft) Note: The maximum altitude, 2133.6 m (7000 ft.), is the maximum altitude at which the specified air temperatures apply. At higher altitudes, the maximum air temperatures are lower than those specified. Humidity: - System on: 8% to 80% - System off: 8% to 80% Electrical input Input voltage: - Low range: - Minimum: 90 V ac - Maximum: 137 V ac - Input frequency range: 57-63 Hz - Voltage switch setting: 115 V - High range: - Minimum: 180 V ac - Maximum: 265 V ac - Input frequency range: 47-53 Hz - Voltage switch setting: 230 V - Input kilovolt-amperes (kVA) (approximate): - Minimum configuration as shipped: 0.08 kVA - Maximum configuration: 0.38 kVA Note: Power consumption and heat output vary depending on the number and type of optional features installed and the power management optional features in use. Heat output Approximate heat output in British thermal units (Btu) per hour: - Minimum configuration: 245 Btu/hr (70 watts) - Maximum configuration: 969 Btu/hr (285 watts) Airflow Approximately 0.85 cubic meter per minute (30 cubic feet per minute) maximum Acoustical noise-emission values Average sound-pressure levels: - At operator position: - Idle: 36 dBA - Operating: 39 dBA - At bystander position-1 meter (3.3 ft): - Idle: 33 dBA - Operating: 36 dBA - Declared (upper limit) sound-power levels: - Idle: 4.7 bels - Operating: 5.0 bels Note: These levels were measured in controlled acoustical environments according to procedures specified by the American National Standards Institute (ANSI) S12.10 and ISO 7779 and are reported in accordance with ISO 9296. Actual sound-pressure levels in a given location might exceed the average values stated because of room reflections and other nearby noise sources. The declared sound-power levels indicate an upper limit, below which a large number of computers will operate. Cabling requirements for Wake on LAN adapters The PC 300PL Personal Computer has a 3-pin header on the system board that provides the Auxiliary 5 volts (AUX5) and wake-up signal connections. Newer Wake on LAN adapters have a single 3-pin header that connects to the 3-pin header on the riser card. Some Wake on LAN adapters have two headers: a 3-pin, right-angle header for AUX5, and a 2-pin straight header for the wake-up signal. These Wake on LAN adapter options include a Y-cable that has a 3-pin system board connector on one end and splits into the 3-pin and 2-pin connectors that connect to the adapter. Chapter 3.
